DXMJ-TV

GMA Davao began operations in 1965 as DXSS-TV channel 7, the first provincial television station in Mindanao. DXSS-TV was inaugurated by Southern Broadcasting Network under the affiliations of GMA Network's predecessor Republic Broadcasting System. Eight years after the successful of the radio station DXSS-AM, the company ventured into television broadcasting as DXSS Channel 7, adopting the brandname RBS TV-7 Davao (now known as ETC TV-7 Davao). The station was subsequently shut down following the declaration of Martial Law by then-President Ferdinand Marcos by the virtue of Proclamation 1081 on September 21, 1972.

Under the ownership of RBS in 1974, DXSS-TV channel 7 was reopened with the variant of the GMA Radio-Television Arts identification, though Republic Broadcasting System, Inc. remained as its corporate name of the network until 1996. The newly relaunched Channel 7 had sported the network's light blue square logo with the network name in white with the circle 7 logo, in its final years the blue circle 7 logo used was similar to those used by the ABC in some United States cities (in 1991 the rainbow colors of red, yellow, green and blue stripes was adopted), and it was also relaunched as an originating station serving Davao City with its first local newscast News at Seven Davao. It also launched its Cebuano drama series Goot da Wanderpol, which syndicated from its co-owned station in Cebu from 1980 to 1985.

On April 30, 1992, following the network's expansion of coverage, DXSS-TV channel 7 was integrated into the Rainbow Satellite Network nationwide satellite broadcast to bring live broadcasts of national and foreign porgramming from Manila-based DZBB-TV, the network's flagship TV station, to viewers in the Davao region, with added local opt-outs to serve local audiences. The new logo which came with rebranding had the name GMA in Sans Serif Century font in a gray metal-like form and a satellite-beaming rainbow in a multicolored stripe based on the traditional scheme of red, orange, yellow, green, blue, indigo and violet.

In 1994, when Southern Broadcasting Network bought the station DXSS-TV channel 7 from Republic Broadcasting System as its partnership, the channel's affiliation was swapped with ABC, whose former station had been closed due to declaration of Martial Law twenty-two years ago, and GMA thus acquired the channel 5 frequency resulting to a callsign change to DXMJ-TV, which has been used till the present. Since the completion of the purchase, GMA Channel 5 Davao became an owned-and-operated station under the ownership of Republic Broadcasting System, which later formally changed its corporate name to GMA Network Incorporated on May 20, 1996, with GMA now standing for Global Media Arts.

In 1999, GMA Channel 5 Davao was re-upgraded into an originating station with the producing its local newscast Testigo: GMA Super Balita for Davao City and several other provinces in southern Mindanao.

In 2005, "Testigo" and "Singgit Davao" were re-launched and were taken under the wing of GMA News & Public Affairs and GMA Entertainment TV Group respectively. In August of the same year, "Singgit Davao" was relaunched as "Kuyaw!" in time for the Kadayawan Festival. GMA Davao's first morning show, Una Ka BAI was launched on October 8, 2007 with Sarah Hilomen, Derf Mais, and MK Sobrecarey as its initial hosts.

On November 10, 2014, following the changes of the network's flagship newscast 24 Oras, GMA News & Public Affairs Davao's local newscast Testigo was re-launched and rebranded as 24 Oras Southern Mindanao. However, on February 1, 2016, the program is the only GMA regional newscast to use the 24 Oras branding after two of its other regional newscasts reverted branding to its original names; which premiered since 1999 and 2008 respectively, following the cancellation was the retrenchment of its staffs and personalities and the closure of the network's regional news department as part of the strategic streamlining happened to all of its regional operations of GMA since two years ago.
